5.9 LM4041-NLM4041-N-Q1 ADJ (Adjustable) Electrical Characteristics (Extended Temperature Range)

All limits T_J = 25°C, unless otherwise specified (SOT-23, see⁽¹⁾), I_RMIN ≤ I_R ≤ 12mA, V_REF ≤ V_OUT ≤ 10V. The grades C and D designate initial Reference Voltage Tolerances of ±0.5% and ±1%, respectively for V_OUT = 5V.

(1) When V_OUT ≤ 1.6V, the LM4041-NLM4041-N-Q1 ADJ in the SOT-23 package must operate at reduced I_R. This is caused by the series resistance of the die attach between the die (–) output and the package (–) output pin. See the Output Saturation (SOT-23 only) curve in the Typical Characteristics section.

(2) Limits are 100% production tested at 25°C. Limits over temperature are made sure through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate AOQL.

(3) Typical values are at T_J = 25°C and represent most likely parametric norm.

(4) Reference voltage and temperature coefficient can change with output voltage. See Section 5.10 curves.

(5) Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change must be taken into account separately.

(6) Thermal hysteresis is defined as the difference in voltage measured at +25°C after cycling to temperature –40°C and the +25°C measurement after cycling to temperature +125°C.
